<Menu to check: [Security]
Are you trying to power off by a method other than pressing the POWER switch?
You cannot power off the server by using software commands such as the
shutdown command. Press the POWER switch to power off the server.
POST fails to complete:
Is the DIMM installed?
At least one DIMM is required for operation.
Is the memory size large?
The memory check may take a time if the memory size is large. Wait for a while.
Did you perform any keyboard or mouse operation immediately after you started the
server?
If you perform any keyboard or mouse operation immediately after start-up, POST
may accidentally detect a keyboard controller error and stops proceeding. In such
a case, restart the server once again. Do not perform any keyboard or mouse
operation until the BIOS start-up message appears when you restart the server.
Does the server have appropriate memory boards or PCI card?
Operation of the server with unauthorized devices is not guaranteed.
Server reboots while running the SCSISelect utility:
Have you modified the Setup settings?
From [Server] - [Monitoring Configuration] - [Option ROM Scan Monitoring] of
Setup, select "Disabled." If [Option ROM Scan Monitoring] is enabled, the
system may reboot while using the SCSISelect utility. Change back the setting
after you finish using the utility.
Fail to access to internal or external devices:
Are cables properly connected?
Make sure that the interface cables and power cord are properly connected. Also
make sure that the cables are connected in the correct order.
Is that device compliant with NEC Express5800/ft series?
